Letters Patent N0. 99,609, dated .February 8, 1870.

SAD-IRON" HEATER The schedule referredto in these Letters Patent and making para ef the same T o all whom it may concern.--

Be it known that I, FERDINAND STADLER, of Philadelphia, in the county of Philadelphia, State of Penn sylvania, have invented a new and useful Improve-- charcoal or any other suitable kind of fuel is burnedA in it, serves to heat the sad-iron, and to keep up the right temperature of the same. By this contrivauce, I am enabled to dispense with the expensive, and, in summer-time, very uncomfortable practice of heating the irons on the stove or range; and, besides, I can keep up the temperature of my sad-iron much more uniformly and with much less expense.

Io enable others skilled in the art to' make and use my invention, I will proceed to describe its construc- `tion and operationA I have my sad-irons cast with a hollow chamber, A, open at the top.

A corresponding cast-iron lid or cover, C, to which the handle H is fastened in the usual way, and which is provided, ou the inner side, with threeprojeetions, p p p, one at the forward end and two at the back, is attached to the body of the sad-iron, by means ofthe hinge h, on one side, and by the spring-catch d on the g other side.

On the bottom of the hollow heating-chamber A, I have a certain number (six) of projections, fr lr lr r lr r, which support a perforated iron plate, x, serving as a grate, and under this grate an open space, g/,wliich is used as an ash-pit, and communicates with the outside by the opening o, which is surrounded by a fender, k, in order to prevent thefalling out of the ashes from the ash-pit.

By the sliding door t', which can be moved up and down by means of the knob t and the slot s, through which a screw, c, provided with a face-plate, n, projects, I am enabled to regulate the draught, and, con-V sequentlygthe temperature of my sad-iron, and l can also stop Vthe draught entirely. Thislatter is done when the iron is not in use, in order to keep up the heat and to save the fuel.

. When I want to use my improved sad-iron, `I have Ito open the lid C, by drawing back the spring-catch d, and after tillingthe hollow chamber A., above the grate x, with -live charcoal or other suitable fuel, I close the lid again. After a few minutes, the sad-iron will then be ready for use. The draught passes in through the opening o and the grate x, and sets Vthe coals in a blaze. The products of combustion escape through the openings g g g, between the projections of the lid p p p, and the iron becomes suciently hot to use it for all purposes for which common sad-irons are now employed.

I know that self-heating sad-irons have been invented and used before, especially sad-irons heated by gas-jets. But for my invention, I claim that it is the 'cheapest-only seven. cents worth ot charcoal is consumed per day-as well'as the most convenient. The chimney through which the products of combustion have to escape, (as used by all former inventors of self-heating sad-irons,) is very, inconvenient for the workman, -because `the j concentrated heat escaping through it scorches his hand, and makes his' head ache. My improved sad-iron, on the contrary, causes the heat to diiuse. It must, with the other products of combustion, escape through three dilferent broad openings, and, consequently, does not molest. the workman.

That I claim as my invention, and desire to secure by Letters Patent, is-

The sliding door t', constructed as specified, and the fender 7c, in Vcombir'iation with the openings g g g, the grate x, 'and the ash-pit y, substantially and for the purpose as set forth.

FERDINAND STADLER.
